T 0 all whom it hwy concern I Be it known that we, FRANK AsHwoR'rH HOLT, machine-maker, a subject of the King of the United Kingdom of Great andresident of Noon Sun House, Whitworth Road, Rochdale, in the countyof Lancaster, England, and

machine-maker, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of 62, Market street, Whitworth, in the county of Lancaster, England, have invented new and useful Improvements in Winding-Machines, of which the following is a specification.

This carrying the machines of the kind ously revolving driving roll is volve a winding such holder ora spool placed upon it or yarn or thread wound thereon, the winding holder being mounted on a support capable of being turned upward invention relatesto mechanism for in which a continuabout an axis and of being turned about another axis in a plane transverse to the axis about which it can be raised."

The object of this invention is to insure by simpler means than have been heretofore provided that the axial lines at the apices of yarn packages shall not point to the side of the axial lines of the driving rolls, on the side remote fromthe axes of movement of the bearers, for at least so long, after the commencement of the winding of the several yarn packages, as such pointing of their axial lines would cause detrimental dispositions of yarn or thread in the yarn packages and such defects and inconveniences as the formation of packages with the ends unduly large andthe intermediate parts unduly small and in the case of soft yarns or threads the pushing of yarn or thread over I the large ends of the packages.

This invention consists in a carrier for a winding holder'around which a conical or like yarn package is to be wound in a machine of the said kind positioned so that the tilting of the carrier and winding holder will counteract or compensate for the tendency of the raising of the carrier about the axis of the movement of the bearer to throw the axial line at the age to the side of the axial line of the drivaxis of movement Specification of Letters Patent.

commencement of so long thereafter the apexof of the bearer from" the winding and for at least as pointing of the axial line at the yarn 'packageJbeing wound around the holder on the s1de of the axial line of the driving roll further from the axis of movement of the.bearer, would involve detrimentaldisposition of yarn in the ,yarn package being wound. This invention further consists in devices insuring that the raising of the carrier shall be accompanied by a corresponding tilting and so insurmg that the axial line of the yarn package shall point in the proper direction for the intended disposition of yarn or thread inthe yarn package, and also in devices by which the tilting of holdermay be adjusted, as may be desirable from time to time, in accordance with changes in the count or thickness or numberthreads to be wou'nd'in a package or in the proportions of the length and diameter of packages to be wound'and the fitting of parts to one another is simplified.

the description of the parts provided or constructed accordmg to this invention but it is to be understood are applicable to winding machines of other kinds in which they may be desirable.

Thethread guide j is mounted similarly to thread guides of machines already known in a carrier is mounted on round and rectangu-larqguide bars Z m fixed in position and is provided-with an oscillatable diew, made "toenter a cam track 2' of the cam g,

the carrier I: having a tubular part 0 to surroundand to be slid upon the round guide bar "Zr and a forked part p-to embrace and to be slid upon the rectangular guide bar m. g is a rod fixed in position andextending lengthwise of the machine for the support of a bearer 1* in the form of an arm for; carrying the holder\ a. The bearer 7 is adapted to be turned about the rod 9. Like the arms used for the support of the holders of winding machines already known; the bearer 1" is provided with a handle 8 connected to it by means of a'rod t furnished with.a rack to having ratchet teeth and serving for use in -moving the holder at from or controlling its return toward or for holding the holder a away from the driving roll 6 4 For the. purpose of" this invention the carrier '2; of the holder a is mounted to turn upon its bearer 1' about van axis which is ofi'setfrom the axis of the rod 9 and crosses over theaxial line of the drivingroll at an angle not greater than a right angle at the side toward the smaller end of a. yarn pack-v age being wound and when the holder a is nearest the driving roll 0 is inclined toward 1 p the axis about which the carrier v swings the radial direction fromthe axis of the rod 9 tothe placeof contact of a yarn package on the, holder a with the driving roll 0 at an angle not less than the angle through which-'. thebearer r swings in any period in which precision of disposition of yarn in a yarnpackage is necessary. Consequently upon the bearer 1 will not become parallelto the radlal direction from the axis of the rod 9 to. the place at which a yarn package bears upon the driving roll 0 until nearly the Qhmit of movement of the carrier v in v the windlng ofayarn package so that, until the bearer 7" in being raised reaches the position it attains when the winding of a yarn package is nearly completed; the swinging of the carrier '0 upon the bearer 1", moving the downwardly pointing smaller end of the holder or downward will move it toward the axis of the rod (1 and so will counteract the tendency of the raising of the bearer r tained by different constructions.

to move such smaller end of the holder a 0UtWaI(l relatively to the driving roll 0 and thereby will cause the smaller end of the at right angles over the axis of the drivingv roll 0 and inclined downward toward it 'so as to make with a straight line from the axis of the rod 9 to the place of contact between a yarn package being formed and thedriving roll 0, an angle not less than thegangle through which the bearer 7' is turned about the rod g'from the commencement to nearly the completion of a yarn package and the bearer 1' is made to extend upward in an The requisite dis- 0 when the holder a is nearest the driving roll;

inclined direction and to afford a bearing for the pivot y. vThe cross head of the pivot 7 has a hole of a V section in its upper part to receive the shank w of the arm 1).

The holder at is mounted on the arm "1; in j a manner similar to thatin whichthe holders of machines heretofore in use are mounted on their supports. The shank w is of a V section in its upper part to fit in the hole of the cross head :20 and is secured in posi tion in the cross head w by means of a setscrew 1. lengthwise by means of the cross head w and a collar 2 secured by a set screw 13 on the pivot y bearing against the arm y I Further for the purpose of this in vention the carrier '0 is provided with a projection [1 made to bear and to present an oblique face against a fixed part 5 so that as any raising of the carrier 0 about the rod g will be accompanied by a corresponding tilting r of the carrier 4) about the axis of the pivot whether or not yarn is wound on the holder The pivot 3 is held in position a a precisely in such form as to tilt the holder a in a proper way; In the ease illustrated the projection 4 is formed as a plate mounted adjustably upon an arm Gsecured by -a set-screw 7 on the shank w the projection being connected to the arm 6 by a pivot 8 and provided with a curved slot- 9 through which is passed a set-screw 10 provided with a washer and screwed into the arm 6 'so that it may secure the projection 4-in posi}; tion after adjustment on the arm'6.

uThe projection may be of any appropriate shape but in the case illustrated is formed with a straight edge 11; The fixed part against which the projection 4 may be made to bear may be of any convenient form and secured in position in any suitable way but in'the case illustrated is represented as 'a stud secured in a collar 12 mounted upon the rod (1 and secured in position by means of a set-screw 13.

5 By the direction of the pivot y' being duly chosen relatively tothe intended tilting of the bearerr provision maybe made for the axis ofthe holder 0, to be kept with any requisite degree of accuracy in some plane 10 parallel and of one relation transversely to the axis 10f the roll 0, as the holder or is raised from the driving roll 0 and by the projectioni t being suitably formed and adjusted the axis oi the holder a may be tilted 1-5 with any degree of precision requisite to keep fit with any requisite degree of accuracy in some plane parallel and of one relation transversely to the axis of the roller c.

The case illustrated shows a construction generally preferable having the line of the axis about which the carrier 1) is turned on the bearer'r passing the holder at at about midway in-its length in order that in the tilting or turning of the carrier 4) the axial line of the holder wand yarn package shall be moved inward at the apical end and outward at the basal end relatively to the axis of the rod 9 about which the bearer is turned.

The yarn may be led to the holder on through the thread guide j ihsingle thread or two or more threads together.

.When the yarn is attached to the spool b 3 and led through the thread guide j and the driving roll 0 is revolving and the spool b is laid against the driving roll 0 yarn is wound upon it and as coils or' layers are successively wound upon it the spool b is raised 40 from the roller 0 and raises the holder on and carrier 0 and-the weight of the holder a and carrier '0 pressing the surface of the yarn wound on the spool b against the surface of the driving holder a to be tilted about the axis of the pivotyj much as holders are tilted about the pivots carrying them in some winding machines already known but with the difference that so'long as yarn is'laid in proper form on the spool b by the traversing to and fro.

- of the thread guide -y' the tilting of the holder at by reason of the disposition of the pivot y relatively to the axisor center lines of the roll a and rod Sq causes the axis or center line of the holder ato be kept approximately in a plane parallel and in constant relation to the axis of the roll'c regardedf transversely to such roll 0. If the yarn wound on the spool 7) should fail from any cause to tilt the holder a about the pivot 1 in correspondence with the raising of the holder a from the roll 0 the projection L bearing against the fixed stud 5 will tilt the holder a and insure that the center line Q5 or axis of the holder a shall remain approxinearly the completion off a said carrier carried by such support to roll 0 may cause the mately in some plane in uniform relation to the axis of the roller 0 in a direction transverse to it. .By the projection 4 being adjustable upon. the arm 6 the tilting of the holder a may be adjusted for the use of spools b of difg ferent tapers or lengths or the winding of yarn singly or in twotor more threads together or the winding of yarn of different counts or thicknesses. The provision for the adjustment of the projection Lalso facilitates the construction and fitting of the apparatus.

The provision of the carrier 0 for a yarn holder 0: to be turned upon a bearer 1 about an axis downwardly toward the driving roll 0 at an angle not less than the angle of the upward swinging of the bearer as winding proceeds from the commencement to enables conical packages of yarn to be wound of very accurate form and true coni cal taper and rounded bases free from loose ,or projecting loops of yarn especially when provision is made for constraining the turning of the carrier v upon the bearer 7" in correspondence with the extent to whichthe holder (1 'is raised from the driving roll a. v n
